I don't absolutely hate this boss,but the fight was just disapointing.Joker injects himself with toxin and becomes...a giant white-skinned clown with a green mowhawk? Quite unfitting for the Joker... Well the design isn't why he's disappointing.It's the fight.Half of the fight is fighting his goons while he watches you.He barely even attacks you! I mean if you make a big bulky toxin-injected Joker,shouldn't half of the fight be brute combat?!

5Rodrigo Borgia - Assassin’s Creed 2

This boss failed in every way, the first part with the clones was terrible as they did nothing, there was no music, the fistfight afterwards was stupid, there was no challenge, the ending scene in the animus sucked, and to top it all off, YOU DON"T EVEN KILL HIM. this last fact is especially bad as this game is about killing those who wronged you, but the person who was the worst is the only one you spare. This boss failed so much on every level.

THIS IS HOW THEY CHOOSE TO END THE PRIME SERIES? WHAT HERE THEY THINKING? - Masterlugia64

7Necron - Final Fantasy IX

The fight is OK, but HE COME OUT OF NOWHERE, also if you beat him, he is NEVER mentioned again. - Masterlugia64

8The Great Mighty Poo - Conker's Bad Fur DayThe Great Mighty Poo is a fictional character appearing in the 2001 video game Conker's Bad Fur Day. He is a giant, opera-singing pile of feces that appears as a boss in the sloprano chapter.

He's not even the final boss, you idiot. - MKBeast

HE IS NOT THE FINAL BOSS - Masterlugia64

9Steroid Joker - Batman Arkham Asylum

10Gary - Bully

It's kind of to be expected that Gary's a weak boss. He's a schemer, not a fighter (like you are).

I like this game! But the final boss, should have been longer:( - nintendofan126

I expected Gary is a powerful boss, but I beat him up easily - Delgia2k

A disappointing boss, for such an awesome game - SmashBall

All you do is it the yellow meteors into him. - Masterlugia64

16The End - Metal Gear Sold 3: Snake Eater

17Titanic Toddler - Zombies Ate My Neighbours

18Psycho Mantis - Metal Gear Solid

He's not a final boss... - Masterlugia64

19The Enchantress - Shovel Knight

She is a joke when compared to the boss rush that comes right before her. - xandermartin98

20Purple Man - Five Nights at Freddy's 3

All you do is make him run around the room until he gets into Springtrap's suit and he dies after that, very disappointing. - Masterlugia64

21Undead Core - Cave Story

It isn't the REAL final boss though. - xandermartin98

22Dark Nova - Kirby: Squeak Squad

Really? A one-eyed dark star?! That's the final boss?! Dark Daroach was awesome, but Dark Nebula just didn't live up to the monster it created of Daroach's corrupted dark form. Come on, Masahiro Sakurai. Is that the best you could come up with? - ModernSpongeBobSucks

Now this is beyond true. Plus, how was K.Rool from Donkey Kong Country 1 a disappointment? Now in the third game, I can understand.

All he does is run away.

26Prince Charming - Shrek the Third

Very disappointing. He doesn't even fight back! Not to mention that when you hit him once he is done! - RalphBob

27Nemesis - Resident Evil 3: Nemesis

28Wily Capsule - Mega Man 7

29Saddler - Resident Evil 4

30Ganon - Link: The Faces of Evil and Zelda: Wand of Gamelon

This was a bad boss but a game this bad couldn't really disappoint with a bad final boss.

31Dr. Fetus - Super Meat Boy

This guy wasn't a disappointment, once you learn the pattern it is not that hard, but it was still a great fight.

Although easy, it was still really cool how all of his attacks were so ridiculous, it really gave the feeling of him being a god.

Perhaps in difficulty, but definitely not in the FEELS department ;( - xandermartin98
